“…It can also provide real-time guidance during fracture reduction and is more portable and less cumbersome for this purpose than traditional fluoroscopy (Chen et al, 2007;McManus et al, 2008;Patel et al, 2009). The portability of ultrasound has been underscored in a recent study that demonstrated its clinical usefulness in the diagnosis of fractures in more austere combat environments (McNeil et al, 2009). The role of sonography in the evaluation of the injured patient is ever evolving.…”

“…48 In addition to eight articles that had not been published at that time, 20,[26][27][28]32,33,41,46 our study includes thirteen other articles not included in that review. 21,22,24,25,29,30,[34][35][36]38,41,43,44 Additional studies were possibly found as a result of a more comprehensive search strategy. Our review reaches similar conclusions, that PoCUS is a useful tool to supplement radiographs for the detection of fractures.…”

“…7,8, Two studies used a second reference standard for some of the patients, either computed tomography when the plain radiographs were not definitive or a daily clinical evaluation for 72 hours with delayed imaging or return to full duty for military personnel. 34,42 Both the medical background and PoCUS training of the operators varied greatly across studies. Sixteen studies (53.3%) had emergency physicians performing and interpreting PoCUS examinations, four studies (13.3%) had surgeons (pediatric, hand, and/or orthopedic), five studies (16.7%) had radiologists or ultrasound fellows or technicians, and four studies (13.3%) included medical students or residents.…”

“…All studies reported both the sensitivity and specificity of PoCUS, and LRs were calculated from these values when the authors did not include them in their manuscripts. Twenty-five studies 7,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][41][42][43][44] were included, ranging from 26 to 653 patients. Collectively, these studies included 2,982 patients and identified 1,200 fractures, with fracture prevalence ranging from 7% to 71% (aggregate prevalence of 40.2%).…”

Objectives: Long bone fractures (LBFs) are among the most frequent traumatic injuries seen in emergency departments. Reduction and immobilization is the most common form of treatment for displaced fractures. Point-of-care ultrasound (PoCUS) is a promising technique for diagnosing LBFs and assessing the success of reduction attempts. This article offers a comprehensive review of the use of PoCUS for the diagnosis and reduction of LBFs. Data source: MEDLINE and EMBASE databases were searched through July 19, 2015. Study selection: We included prospective studies that assessed test characteristics of PoCUS in 1) the diagnosis or 2) the reduction of LBFs. The methodological quality of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Data extraction: Thirty studies met inclusion criteria (n = 3,506; overall fracture rate 48.0%). Test characteristics of PoCUS for the diagnosis of LBFs were as follows: sensitivity 64.7%-100%, specificity 79.2%-100%, positive likelihood ratio (LR) 3.11-infinity, and negative LR zero-0.45. Sensitivity and specificity for the adequate reduction of LBFs with PoCUS were 94%-100% and 56%-100%, respectively. PoCUS diagnosis of pediatric forearm fractures in 10 studies showed a pooled sensitivity of 93.1% (95% confidence interval [CI], 87.2%-96.4%) and specificity of 92.9% (95% CI, 86.6%-96.4%), and PoCUS diagnosis of adult ankle fractures in four studies showed a pooled sensitivity of 89.5% (95% CI, 77.0%-95.6%) and specificity of 94.2% (95% CI, 86.1%-97.7%). Conclusion: PoCUS demonstrates good diagnostic accuracy in all LBFs studied, especially in pooled results of diagnosis of pediatric forearm and adult ankle fractures. PoCUS is an appropriate adjunct to plain radiographs for LBFs. RÉSUMÉObjectifs: Les fractures des os longs (FOL) figurent parmi les blessures traumatiques les plus fréquentes au service des urgences, et les traitements les plus courants des fractures avec déplacement consistent en la réduction et l'immobilisation du membre touché. L'échographie au point de service (EPS) est une technique prometteuse dans le diagnostic des FOL et dans l'évaluation de la réussite des tentatives de réduction. Aussi les auteurs ont-ils procédé à un examen exhaustif de la documentation médicale sur l'utilisation de l'EPS dans le diagnostic et la réduction des FOL, et ils font état des résultats dans le présent article. Source de données: Des recherches ont été effectuées dans les bases de données MEDLINE et EMBASE jusqu'au 19 juillet 2015 inclusivement. Sélection des etudes: Ont été retenues des études prospectives visant à évaluer les caractéristiques de fonctionnement de l'EPS au regard 1) du diagnostic ou 2) de la réduction des FOL. La qualité méthodologique des études sélectionnées a été évaluée l'aide de l'outil Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). Extraction des données: Trente études respectaient les critères de sélection (n = 3506; taux général de fracture : 48,0 %). Les caractéristiques de fo...

“…Bedside US also provides clinically useful information in settings outside of the traditional hospital, including military combat zones, 18 disaster areas, 19 and developing countries. 20 Although not traditional medical settings, it is important to have knowledge of how to use bedside US to assist in decision-making, such as evacuation protocols or prioritization of treatment.…”

Objectives: Understanding history, physical examination, and ultrasonography (US) to diagnose extremity fractures compared with radiography has potential benefits of decreasing radiation exposure, costs, and pain and improving emergency department (ED) resource management and triage time. Methods:The authors performed two electronic searches using PubMed and EMBASE databases for studies published between 1965 to 2012 using a strategy based on the inclusion of any patient presenting with extremity injuries suspicious for fracture who had history and physical examination and a separate search for US performed by an emergency physician (EP) with subsequent radiography. The primary outcome was operating characteristics of ED history, physical examination, and US in diagnosing radiologically proven extremity fractures. The methodologic quality of the studies was assessed using the quality assessment of studies of diagnostic accuracy tool (QUADAS-2).Results: Nine studies met the inclusion criteria for history and physical examination, while eight studies met the inclusion criteria for US. There was significant heterogeneity in the studies that prevented data pooling. Data were organized into subgroups based on anatomic fracture locations, but heterogeneity within the subgroups also prevented data pooling. The prevalence of fracture varied among the studies from 22% to 70%. Upper extremity physical examination tests have positive likelihood ratios (LRs) ranging from 1.2 to infinity and negative LRs ranging from 0 to 0.8. US sensitivities varied between 85% and 100%, specificities varied between 73% and 100%, positive LRs varied between 3.2 and 56.1, and negative LRs varied between 0 and 0.2. Conclusions:Compared with radiography, EP US is an accurate diagnostic test to rule in or rule out extremity fractures. The diagnostic accuracy for history and physical examination are inconclusive. Future research is needed to understand the accuracy of ED US when combined with history and physical examination for upper and lower extremity fractures.ACADEMIC EMERGENCY MEDICINE 2013; 20:1-15 © 2013 by the Society for Academic Emergency Medicine E xtremity injuries are among the most frequent reasons for visiting the emergency department (ED). These injuries are significant, comprising over 42.4 million injury-related visits to the ED in 2006. 1The typical work-up of the injured patient generally involves a medical provider obtaining a history and physical examination, often followed by radiologic imaging. However, many times the radiologic imaging may be negative or inconclusive, which calls to question whether the imaging contributed to the management or outcome of the patient. Studies have shown that often the imaging obtained is unnecessary and results in radiation exposure to patients and increased ED wait times. 2There is a low rate of positive radiography when assessing for fractures as evidenced by a retrospective review by Bentohami et al.,3 in which only 50% of upper extremity x-rays showed fractures, and another ...
